Walters Way and Segal Close

Walters Way and Segal Close are two cul-de-sacs in Lewisham, South London. The twenty homes they contain are unusual, both in the way they look and in the way they were conceived and built. Designed by modernistarchitect Walter Segal, they were part of a council-run scheme that allowed ordinary people to build their own homes.

The success of the project proved influential for the self-build movement which has grown over the last 30 years, gaining widespread exposure through TV shows such as 'Grand Designs'.

To celebrate 30 years since the completion of Walters Way, communityresident Alice Grahame has authored a comprehensive 'coffee-table' book examining the history of the self-builders, the current residents and the various modifications they have made, together with original sketch plans and fabulous photographs by Taran Wilkhu.

Key to the enduring appeal of these houses is the 'Segal method' of construction which, owing to the sloping nature of the site, led to the use of timber stilts rather than traditional foundations.

Segal took the design back to the first principles and reduced it to its simplest elements - relying on post-and-beamtimber frames, and a structural feature known as a St. Andrew's cross - two lengths of timber in an X-shape giving the buildingrigidity, holding it together both in tension and compression.

Back in the 1970s, it did seem like something of a perfect storm - there was a housing crisis, a lot of people on waiting lists, and certain people in place on the council who seemed amenable to doing experimental things - various radical characters such as Colin Ward the anarchist writer and Walter Segal - who had a fortuitous meeting of minds.

Everyone goes to planning in the normal way, we don't have a power of veto over what neighbours do beyond what the local authority would decide. The houses are locally listed with Lewisham council, but not nationally with Historic England. No one has ever applied to be listed because everyone wants to be able to modify their house if they wish.

The community collectively own the road, we have a 'residents association' to manage the pump and the street lights. It melds the community together, whenever there's an argument it's always about parking, as it is quite confined in the cul-de-sac.

DBW: Although the public interest in self-build seems to have grown through renovationprogrammes and 'Grand Designs', is Walters Way too aspirational almost?

AG:

When the houses were originally built it was a councilprogramme aimed at those on low incomes who were in need of housing. But then people were allowed to buy their own homes, initially part-rent, part-buy, and gradually over time everyone bought all of their homes. Then they were sold on the open market and the houses have since been absorbed into Londonhouseprices.

An estate agent The Modern House really likes these houses now, and promotes their architectural significance, which has pushed up the prices, plus the increased connectivity with the Overground. However, some mortgage companies and insurance companies don't like them, surveyors don't like them, some members of the public don't like them, perhaps because of their unconventionality. So, they are still less than a brick-built house of the same size would be in the area.

DBW: Segal really believed in the transformational power of architecture and creativity through self-build, didn't he?

In the book one of the self-builders, Pauline Kennedy, who with her husband built their house in Segal Close, talks about how Segal was very good at making people believe that they could do it and that it wasn't beyond their capabilities, even if they had no building experience. She says it made her realise that she could achieve more in other areas of her life. She and the other self-builders talk about the confidence it gave them to take on other challenges.

Segal was all about using everyday materials, things you could just buy, like the wood wool slabs he used in his very first design in Switzerland in the 1920s. The timber is mostly softwood, all capable of being bought locally, so as to minimise cutting.

Because of that, people have been able to update or improve their house to their own lifestyles. The houses are bolted rather than cemented or glued together, so you can open up panels and adapt the space as you want.

We've integrated cradle-to-cradle materials, others have built things like a yoga studio or bigger decking for outside space. Other people have installed eco-friendly solutions like triple-glazing, because you can change the shape of your windows, which if it were a brickhouse that would be something of a mission.

DBW: Was Segal ahead of his time in terms of using structural timber, which is now also increasing in popularity, and how does it perform in practice here?

AG:

There's no damp at all because we're raised on stilts off the ground. The timber is treated every few years. Segal's design of the overhanging roof is important. He used standard softwood and pine for the majority of the fascia, with the detailing you get very little weathering, so he was aware of how you could solve a longevity problem with a detail like that.

We don't get subsidence or cracks, despite being on south LondonClay, for several reasons. We don't have heavy foundations - just concrete plies, the house is raised up on stilts and is lightweight. We are not bothered by tree roots because we are raised above them. The house isn't fixed to the ground or glued together. It rests on paving slabs on the piles and the house is held together with bolts, it has a tendency to shift a bit - we had to cut a new bathroom door to fit the shape because the frame was no longer square.

DBW: What lessons do you think Walters Way and Segal Close have for contemporary urban planners and the like?

AG:

It would be really good if urban planners, architects and housingprofessionals, would come and look at Walters Way and see that by designing a house well, quite a cohesive community was created, as well as houses that people really want to live in. Everyone really likes living here; the open plan living, the adaptability to changing needs and lifestyles is really important.

With regard to modern micro homes, I think Segal would be preoccupied with what they are actually like to live in, are they really fit for living in? With these houses, there's no space wasted, and designers could learn a lot from them.

DBW: Despite his achievement with these projects, do you think Segal would be disappointed 30 years on to see that they haven't been adopted on a wider scale across London or elsewhere?

AG:

I think he would be disappointed that it hasn't gone mainstream. Seen as how these houses are relatively quick and cheap to build, nice to live in, why not roll it out to the public?

If you hear the stories of the original self-builders, it was hard work, but I don't see why it couldn't be made a lot easier now. There are similar ideas with WikiHouse, the Y-Cube and PLACE:Ladywell, but they are all mostly seen as 'emergency housing', something that you do while waiting for proper housing to be built. It hasn't taken off to anywhere near the extent that I think he would have liked.
